1000 is a very high dosage. You can take Pancreatinum 30CH, 2-3 drops in a tsp of water thrice a day. Depending on your symptoms, you might be needing more medicines. Pancreatinum alone might not be sufficient or indicated. I suggest you consult a good homoeopathic doctor near you before starting the medication. Hope this helps.
Maintain half an hour gap between food/drink/any other medicines and homeopathic medicine.
Avoid any strong smell in the mouth while taking medicine e.g. camphor, garlic, onion, coffee, hing
